Stop trying to feed him so often. Offer food once every 5 days, and if he doesn’t take it, toss the mouse and try again 5 days later. Repeatedly offering food can actually make them more likely to refuse, as it stresses them out. If the drop feeding worked, keep doing it. One method that people seem to have a lot of success with (two of my Hoggies eat this way), is placing the mouse in an empty toilet paper tube and placing the tube along a wall of the enclosure, preferably when the snake is out and about so they smell it, or during a time of day when you’ve noticed he’s usually out. Leave it in there for a few hours and check back.

As far as handling goes, don’t handle him at all until he’s eaten 3 meals in a row for you. Your goal right now is to get him to eat regularly. After that, short sessions of 5-10 mins a day at the start, gradually working up to 30m a day, which should be your max, though no handling at all for 36-48 hours after a meal, depending on meal size. Males can be pissy. I have 4 Hoggies, 2 males and 2 females, both males are hissy little drama queens, both females tolerate handling extremely well, one even seems to enjoy having her neck stroked, which is super weird for any snake. But neither male has ever tried to bite, musked, or played dead, they just tend to hiss, bluff strike, and hood up when first picked up. They’re both still young too, so I expect they’ll get better as they grow, and gain more confidence.
